An early warning has been issued for a vulnerability in the n8n npm package that could allow an anonymous bypass of an approval gate. Users of affected versions are advised to upgrade.
What happened
An early warning has been issued regarding a vulnerability in the n8n npm package. The issue involves a potential bypass of an anonymous approval gate through the reuse of a resumeToken over the chat WebSocket. This could allow a party without an account to release an execution waiting at an approval gate. The vulnerability has been addressed in versions 2.37.7 and 2.38.2.
The affected versions of n8n are extensive and include multiple version ranges. Users are advised to check their current version against the provided list to determine if an upgrade is necessary.
What to do about it
- Check your current version of n8n against the affected version ranges provided.
- Upgrade to n8n version 2.37.7 or 2.38.2 or later to remediate the vulnerability.
- Monitor the provided sources for any updates or additional information regarding the vulnerability.
